If you have a slight leak at the water pump shaft, tightening the packing nut slightly will probably stop it. 1/4 to 1/2 turn of the nut is usually enough, if the pump is in good condition. You don't want to over-tighten the packing. In some cases, a water pump can leak air into the cooling system when the engine is running, especially at higher speeds. That can lead to overheating. Be sure the water pump is lubricated properly, and be sure the fan belt is properly adjusted. The radiator hoses need to be in good condition and the engine needs to be in a good state of tune. Be sure the fan is not on backwards. It must pull air from front to back.

Check for collapsed hoses, or mushy hoses.
An air pocket trapped in the engine could reduce coolant flow. Was the water distribution tube checked? An out of clearance water pump impeller could cause cavitation and reduced coolant flow. Also check your belts. A loose or slipping belt would be both reduced water pump and fan speed. The belt should not sit all the way into the bottom of the pullet it should ride against the sides of the pulley.
